OBJECT-ORIENTED SOFTWARE LANGUAGE NOW AVAILABLE ON CRAY RESEARCH SYSTEMS

OBJECT-ORIENTED SOFTWARE LANGUAGE NOW AVAILABLE ON CRAY RESEARCH SYSTEMS
 C++ Language Can Speed Application Development, Solution Times
 EAGAN, Minn., July 30 /PRNewswire/ -- Cray Research, Inc. (NYSE: CYR), today unveiled a compiling system that allows users to program in a revolutionary computer language, making it faster and easier to create application programs and solve complex scientific and industrial problems on the company's supercomputing systems.
 The new compiling product, Cray C++ Compiling Systems 1.0, places the supercomputer leader at the forefront of a trend toward "object- oriented" programming, according to Irene Qualters, Cray Research vice president of software. The new compiler allows Cray Research system users to program in the latest version of C++, an evolving computer language that is based on object-oriented programming. This programming approach allows users to create supercomputer-level soauto engineers work with chassis parts, engines, or other automotive components; and mathematicians are concerned with matrices. C++ allows such users to program in these terms, resulting in data structures that more closely mimic the real-life behavior of these objects. Once created, the data structures -- referred to as "objects" -- can be linked like building blocks to create full applications programs. The objects can then be stored for reuse or further development work, and can be shared with other researchers. More traditional programming approaches can require users to spend weeks or months redefining data structures for each new application.
 Cray C++ Compiling System is an enhanced supercomputer version of UNIX Systems Laboratories' C++ Language System 3.0.1, and operates in conjunction with the existing Cray Standard C Compiler. The new Cray Research product runs on all of the company's supercomputer systems, from the entry-level CRAY Y-MP EL system to the top-of-the-line CRAY Y- MP C90 system. Cray Research has licensed the new product to two undisclosed customers.
 Qualters said the Cray C++ Compiling System includes "class libraries," or blocks of ready-made software code, for agreed-upon concepts such as I/O streams and complex numbers. With class libraries, programmers can more quickly develop new applications software and have more time to focus on high-level concepts in their disciplines, she said.
 "Cray Research is in the business of providing fast solutions through high-performance simulations," Qualters said. "We are always looking for ways to make our supercomputer systems easier to use so that customers can harness the power of these systems. This new object- oriented programming language will make it quicker and easier to develop more effective solutions for existing problems, as well as for complex, emerging problems."
 According to Cray Research, object-oriented programming is an evolving programming method in the high-performance computing arena. Last month, the company announced Cray Research IRIS Explorer, an object-oriented application building environment based on Silicon Graphics' IRIS Explorer software product, which was written in C++. "Advanced application tools like Cray Research IRIS Explorer would not be possible without C++," Qualters said. "We view this programming approach as an important standard for the future."
 "Several of the code development projects at Sandia National Laboratories are using object-oriented programming techniques to meet the challenges of quickly developing defect-free software with limited resources," said Mike McGlaun, manager, computational physics research and development at Sandia Laboratories. "These codes include three- dimensional shock physics codes, three-dimensional fluid dynamics codes, and three-dimensional mesh generation codes. Our C++ codes are running efficiently on our CRAY Y-MP system, our workstations, and our massively parallel computers. C++ represents the best compromise between efficiency and functionality. Object-oriented programming is giving us a competitive advantage in today's complicated world."
 Cray Research now provides industry-leading optimizing compiling systems for C++, C, Fortran, and Ada on the company's full supercomputer product line. The optimizing compilers automatically vectorize and parallelize software code to take advantage of these capabilities of Cray Research supercomputing systems, leading to faster solutions.
 Cray Research compiling systems enable scientists and engineers to write efficient computer programs using standard languages, without having extensive knowledge of the supercomputer hardware.
 Cray Research creates the most powerful, highest-quality computational tools for solving the world's most challenging scientific and industrial problems.
